Acquaintance with The underground city of Kish | a sample of flume digging art in Iran
The underground city of Kish which is also called: the Qanat of Kish, the flume of Kish and the underground city of flume, is one of the historical and tourism attractions of Kish Island which its antiquity belongs to more than 2500 years ago.
The flume is the Persian equivalent of Qanat and is said to a construction which was been used to lead underground water in the past. From long time ago, the art of flume innovation was especially for Iranian people and was in their monopolization and due that the antiquity of some of the flumes of Iran belongs to 6000 years ago, the Iranian people can be known as the main owner of the flume digging art.
The flume of Kish is almost 15 kilometers long and was created in the depth of 14 meters of the earth. This flume has the area of almost 10000 m2 and is not comparable with other qanats in different part of Iran by its length and the depth of the pits. This eye-catching construction was created without advanced tools and by tools such as adze and pickaxe and the effects of these tools still can be seen on the ceiling.
Wonderful structure of the flume of Kish
There are different elements which caused this flume to be known as an interesting and special sample of flumes. In continuation, we will review some of these elements:
Amazing firmness of the flume
The success reason of the constructors of the Kish flume in innovation of this construction, is the ingenious usage of a layer of “Maaren” clay on the earth which duplicate the importance and the value of this attraction. The “Maaren” clay is a kind of bole clay that in normal form is soft and flexible and it changes by being placed in exposed to the air. In the event that this clay, loses 1/3rd of its bulk which is water, its structure changes to a rigid form and starts cracking. Constructing this flume in a layer of “Maaren” clay is one of the reasons of its durability and sustainability due that this place always is wet and the unique property of the Maaren clay guarantees its stability.
Perpetual cool air underground
One of the properties of the Qanat of Kish, is its cool and temperate weather which doesn`t change all over the year. There is no difference that in which season of the year you enter inside the flume, in all over the year the temperature of this underground construction is between 22 to 25 degrees Celsius and makes your sightseeing pleasant. This temperate weather also keeps the water in suitable temperature and keeps its quality for drinking.
Coral ceiling with million years of antiquity
This ceiling is full of oysters and creatures which they changed to fossils and they are clearly visible. It`s enough to look upward while being inside the flume, to realize these fossils which have million years of antiquity and are placed next to each other. The experiments which are done in Munich University on some of these fossils shows the antiquity of this ceiling between 53 to 570 million years and shows the long life of this ceiling.
Natural refinery | A valuable and digestible water
The water that flows in the Kish flume, is the result of seasonal rainfall in the island. Corals act as a natural filter and the water refines by passing them and is saved in the layers of the Maaren clay. The ships also brought this water for consuming and selling or exchanging with other goods to the countries around the Persian gulf, because around the 5th and 6th century A.H, the Kish island was trade center of the Persian gulf and Oman sea and its drinkable water had high value in the countries around the Persian gulf.
Overcoming the low slope of the earth
The direction of all of the flumes starts from the height and get to the first place of the water appearance. Kish island doesn`t have much height and its low slope could cause problems to the water movement. The height of the Kish flume in the maximum gets to 45 meters & this caused that this attraction to be a unique sample of the flumes.
